Independent Auditors' Report on Internal Accounting Control
The Board of Directors and Shareholders
IDS Money Market Series, Inc.:
In planning and performing our audits of the financial statements of IDS Cash
Management Fund (fund within IDS Money Market Series, Inc.), for the year
ended July 31, 1997, we considered their internal control structure,
including procedures for safeguarding securities, in order to determine
our auditing procedures for the purpose of expressing our opinion on the
financial staements and to comply with the requirementso fo Form NSAR,
not to provide assurance on the internal control structure.
The management of IDS Money Market Series, Inc. is responsible for
establishing and maintaining a system of internal accounting control.
In fulfilling this responsibility, estimates and judgments by management
are required to assess the expected benefits and related costs of internal
control structure policies and procedures. Two of the objectives of an
internal control structure are to provide management with reasonable,
but not absolute, assurance that assets are safeguarded against loss
from unauthorize recoreded properly to permit the preparation of financial
statements in conformity with generally accepted accounting principles.
Because of inherent limitations in any internal control structure, errors
or irregularities may occur and not be detected. Also, projection of any
evaluation of the structure to futrue periods is subject to the risk that
it may become inadeequate because of changes in conditions or that the
effectiveness of the design and operation may deteriorate.
Our consideration of the internal control structure would not necessarily
disclose all matters in the internal control structure that might be
material weaknesses under standards established by the American Institute
of Certified Public Accountants. A material weakness is a condition in
which the design or operation of the specific internal control structure
elements does not reduce to a relatively low level the risk that errors or
irregularities in amounts that would be material in relation to the
financial course of performing their assigned functions. However, we noted
